Every Pelican Protector Case uses an open cell core wall construction which is actually stronger and lighter than a solid core wall. An incredibly lightweight space-age resin: ultra high impact structural copolymer polypropylene, provides 4 times the strength to weight ratio over conventional injection molding, unaffected by dents, scratches or corrosion. Multiple massive easy open Double Throw ABS Latches and .250 neoprene closed cell "O Ring" and exclusive automatic purge valve to equalize pressure, provides up to 30 feet watertight, crushproof and air tightness for the ultimate protection.
